cwRsync doesn't want to work

Question

rsync

Can't get cwRsync to work. It asks for a password, then it cuts out. Googling for this error has not yielded any results. Tried to run with the -e ssh key, the result is the same.

C:\Users\i\Documents\projects> rsync mydata [email protected]:~/tmp
[email protected]'s password:
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [receiver=3.0.6]
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(610) [sender=3.0.7]

Answer 1

A few years ago I wrote a batch file to backup a folder from a working computer to a router. I do not remember the details, but everything works now. Try to figure it out / play around with the keys.
- set CYGWIN=codepage:utf8
echo %DATE% %TIME% Starting %0 >> %temp%\backup.log
rsync -e "ssh -p 12233 -l admin" -P -avz --delete --delete-after --rsync-path=/opt/bin/rsync /cygdrive/D/docs myrouter.dyndns.org:/home/backup/ 2>> %temp%\backup.log
echo %DATE% %TIME% Done >> % temp%\backup.log
exit

Answer 2

Here I found how to debug with such an error:
samba.anu.edu.au/rsync/issues.html
On a remote server, I made an rsync-debug file:
#!/bin/sh
ulimit -c unlimited
strace -f rsync "${@ }" 2>~/tmp/rsync-$$.out
Launched rsync with --rsync-path=~/rsync-debug
This resulted in a file with debug info from strace:

To be honest, it’s not very clear, except that it can’t find any file /etc/ld.so.nohwcap

Answer 3

Create folders according to where you installed rsync - something like
C:\Program Files\cwRsync\home\Administrator and
C:\Program Files\cwRsync\home\Administrator\.ssh (folders in Windows starting with a dot are created mkdir)
I backed up postgre on fedora with rsync via windows ssh, I had similar errors. Using
regmon.exe, I looked where the ssh.exe process was looking for the ".ssh" folder and created it there.

Answer 4

something like this:
1. Create keys:
ssh-keygen -t rsa -N '' -fc:\tools\backup\id_rsa
2. Upload them to the server
rsync -av "/cygdrive/c/tools/backup/id_rsa.pub" [email protected]:.ssh/authorized_keys
3. Data upload proper:
set IN=/cygdrive/c/backups
set OUT=KW01
set LOGIN=XXXX
set HOST=ch-s0XX.rsync.net
set EXCLUDE= --exclude=files --exclude=images/avatars
set CYGWIN=nontsec
set HOME=c:\tools\backup
rsync -e ssh -prltzvv --delete --modify-window=10 %EXCLUDE% %IN%/ %LOGIN %@%HOST%:%OUT%/
